Constructional Features 
       Top centerline discharge, self-venting casing arranged for back pull-out. Fully confined gasket. Foot support under casing for maximum resistance of misalignment and distortion from pipe loads . 
       ANSI-B-16.5 (Class 150) flanges standard, ANSI-B16.5 (Class 300) optional for working pressure to 2550 kpa with 3mm corrosion allowance. 
       For maximum corrosion , erosion resistance casting is supplied without tapped openings but gauge and drain plug openings are provided when specified. 
       Impeller matched to casing for high efficiency and low NPSH. Fully open, has partial shrouds for maximum vane support without high thrust iherent in closed impellers. 
       Stuffing box pressure reduced and entrance of solid prevented by back pump-out vanes. Large smoothly contoured flow passages combine best slurry and solid handling ability. 
       Impeller is locked on shaft with impeller lock-nut and are sealed by PTFE gasket. State of the art casting methods smoothest possible surfaces for highest efficiency. 
       All impellers are statically and dynamically balanced.
